It's good, but not her best.
The only scenes that saved the video are the mortal kombat fight, breakdown, last chorus
The last chorus was the worst part. If they would have added some "oomph" to the chorus (ad-libs would've been amazing) and the dancing would have been good, the video would have been perfect.
question about the OP: hasn't Britney sold 210 million records? 217 including S&S. Just saying. Btw i recall reading she is the 3rd/4th/5th most-awarded artist ever. That MJ has 500+ awards, Whitney is 2nd with like 490 and then Mariah with Britney and Janet are almost the same with awards from 410 to 450. is that true?
